Study Notes
Ocean Currents and Movement
- Ocean covers 71% of Earth
- Ocean is in constant motion, carrying energy and objects
- Ocean currents are consistent paths of moving water
- Ocean currents carry objects and organisms across the globe
Ocean Currents and Energy Transfer
- Ocean currents transfer energy from the sun
- Water at the equator receives more solar energy
- Warmer currents move away from the equator, carrying this energy
- Colder currents near the poles receive less solar energy
Ocean Currents and Locations
- Ocean currents can carry objects long distances
- Shoes from a ship washed ashore in Oregon, Hawaii, and Japan illustrate this
- Warm currents coming from the equator can warm a location
- Cold currents coming from the poles can cool a location
Major Ocean Currents
- Ocean currents form gyres (large circular patterns)
- Gyres include the Indian Ocean, North Pacific, South Pacific, North Atlantic, and South Atlantic Gyres
- Ocean currents affect surface temperatures at different locations
